brand new 7735HS. Comes up fine on a first boot, running 4K @ 120hz (119.9something). However every time it falls asleep (power management), once you wake it up it will fail to turn on the display (no signal). Only works on a cold boot. Any ideas?
Install latest chipset drivers from AMD, also latest GPU driver. Me personally I set up my monitor to never sleep. I use button to turn off monitor and my machine has everything related to power saving disabled.
